Substitute Part Grouping Explanation

The 1812GC682KAT1A qualifies as a substitute for the 1812SC682MAT1A based on the following substitution criteria:

Matching Parameters:

• Capacitance: 6800 pF (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Package / Case: 1812 (4532 Metric) (identical)
• Physical Dimensions: 0.181" L x 0.126" W (4.60mm x 3.20mm) (identical)
• Thickness (Max): 0.110" (2.80mm) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)

Upgraded Parameters:

• Voltage - Rated: 2000V (2kV) versus 1500V (1.5kV) — higher voltage rating provides enhanced safety margin
• Tolerance: ±10% versus ±20% — tighter tolerance specification

The substitute part maintains all critical mechanical and thermal characteristics while offering improved electrical specifications. The higher voltage rating and tighter tolerance make this part suitable for applications where the original specification can accommodate these enhancements.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC682MAT1A and 1812GC682KAT1A are active production parts manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1812GC682KAT1A offers superior electrical specifications with a 2kV voltage rating and ±10% tolerance compared to the 1.5kV rating and ±20% tolerance of the original part. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part is suitable for applications where the enhanced voltage margin and tighter tolerance are compatible with design parameters. Both parts share identical mechanical footprints, thermal characteristics, and moisture sensitivity ratings, ensuring direct compatibility in PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC682KAT1A directly replace the 1812SC682MAT1A in existing designs?

A: Yes, the 1812GC682KAT1A is mechanically and thermally compatible with the 1812SC682MAT1A. Both parts use the identical 1812 (4532 Metric) package with matching physical dimensions (0.181" L x 0.126" W, 4.60mm x 3.20mm) and thickness (0.110", 2.80mm). PCB layouts and assembly processes require no modification.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating and tolerance. The 1812GC682KAT1A has a 2kV voltage rating versus 1.5kV for the 1812SC682MAT1A, and a ±10% tolerance versus ±20%. Capacitance, temperature coefficient, operating temperature range, and all mechanical specifications remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Both are active production parts from KYOCERA AVX with equivalent regulatory status.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. If the application operates at or below 1.5kV, either part is suitable. If higher voltage margin is desired or if the circuit operates above 1.5kV, the 1812GC682KAT1A is the appropriate choice. The tighter ±10% tolerance of the substitute part may also be preferred in applications requiring stricter capacitance control.

Q: Is inventory availability a factor in part selection?

A: The 1812GC682KAT1A has significantly higher inventory availability (12729 pieces) compared to the 1812SC682MAT1A (979 pieces). For high-volume production or long-term supply chain planning, the substitute part offers better stock availability.
